New research indicates that individuals who stop using new weight-loss injections like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who halt traditional diet and exercise programs.
Published data in a leading medical journal shows that while obese individuals can lose substantial amounts of their total mass while using the jabs, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"Users purchasing such medications should be cognizant of the potential of quick rebound weight gain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.
That rate of recovery means a return to original weight in about 18 months.
Comparing Approaches
The analysis, which examined 37 of trials involving over 9,000 of participants, contrasted the outcomes of these new drugs with older methods.
Researchers emphasize that people who lose weight through diet and exercise generally experience a more gradual creep back—perhaps 0.1 kg a month—once they finish.
Explaining the Rapid Regain
Nutrition scientists propose the mechanism of the jabs explains the heightened regain.
These medications mimic a natural hormone called GLP-1, which moderates appetite.
"Long-term administration of the hormone concentrations far above than normal might result in the body to generate a reduced amount of its own natural hormone, and could diminish responsiveness to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication results in appetite is unsuppressed, making binge eating much more probable."
A Chronic Condition?
The NHS suggest the injections for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians say that, considering the significant potential of relapse, the treatment should be considered life-long.
This view is reinforced by pharmaceutical companies, who state that the findings "highlight the persistent character of excess weight," comparing it to managing diseases like high blood pressure.
User Experiences
Users who have come off the jabs describe a sudden return of appetite.
"I experienced a trigger that goes on and I was suddenly ravenous," said a patient.
This challenge is worsened if individuals have not established lasting lifestyle or habit changes during therapy.
Widespread Adoption
Figures indicate that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Adoption is greater among females compared to men.
- The middle-aged age group shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than public health services.
In conclusion, clinicians emphasize that while the jabs are effective agents for weight loss, they are not a magic fix and lasting health benefits hinges on combined lifestyle management.
